You can charge your phone through those pins, that is all.
There is no audio output possibility (only theoretical)
Maybe simple other half with easier access to charge pins (or wireless charging), then mating contacts on the car-phone-holder side.
Bluetooth could be used for audio transfer.
Well thanks, so i think i will do something for the charging and use bluetooh for audio
Not sure if it has been said but a other half with a sim card slot giving better worldwide 3g bands would be a big seller. Especially in North America.
I am sure that the first one has been suggested before, but yeah...
So a radio transmitter other half and maybe a multimeter other half might be useful for many of us over here

Hmmm.. that multimeter sounds doable, up to certain safe voltages.
I would use somekind of isolation anyway.
--edit--
Maybe something really simple for starters; https://www.sparkfun.com/products/retired/10956
--> Replace atmel with an I2C A/D Converter
--> Add I2C isolator and tiny isolated stepup DCDC converter for safety of your phone.
Defaults specs could be something like
voltage (0-30VDC, 0.05V resolution)
current (0-500mA, 1mA resolution)
resistance (0-100kΩ)
--> Make some modifications to the analog circuit
--> add some analog switches for different ranges
--> take some parts from this thing here http://www.eevblog.com/projects/ucurrent/
Biggest problems i can see here is the attachment of test leads and safety - and not making it too thick.
Who remembers the old AirUI on the N9?
Well, what about having a OH that brings a touchless interface?
...
They are probably both based on on Microchip MGC3130.
Main problem here is that TOH is on the backside of the phone...
unless make whole phone act as center electrode, and side-electrodes could be placed on TOH edges.
This propably doesn't work when holding phone on your hand, but might work when phone is on 'non-conductive' surface.
Anyways MGC3130 devkit in order.
I noticed that tohiri could also be used for simple gesture detection - track heat of your hand, but it is depending on temperature difference.
